The Simultaneous Algebraic Reconstruction Technique (SART) is an iterative algorithm used primarily in the field of image reconstruction, especially in computed tomography (CT). SART is part of a broader class of techniques that solve the inverse problem of reconstructing an image or object from its projections, which can be seen in various imaging modalities beyond CT, including medical imaging and industrial applications.

Townsend discharge refers to the phenomenon in gas physics and electrical engineering where an electrical discharge occurs in a gas due to the ionization of gas particles. Named after the physicist J. S. Townsend, who studied the behavior of electric discharges in gases, this process is fundamental to understanding how gases can conduct electricity under certain conditions. In the Townsend discharge process, when a sufficiently high voltage is applied across two electrodes in a gas, free electrons are accelerated towards the positive electrode.

The term "Iraqi nuclear physicists" typically refers to scientists and researchers in Iraq who specialize in nuclear physics and related fields, including nuclear engineering, nuclear chemistry, and radiation science. Historically, Iraq has had a nuclear program, especially during the late 20th century, which aimed at developing nuclear technology for various purposes, including energy production and scientific research. This program was notably active during the regime of Saddam Hussein.

A carbon label is a label or certification that provides information about the carbon footprint of a product or service. It indicates the amount of greenhouse gases, specifically carbon dioxide (CO2) and other carbon compounds, that are emitted during the production, transportation, use, and disposal of that product or service. The goal of a carbon label is to inform consumers and businesses about the environmental impact of their choices, enabling them to make more sustainable decisions.

Bohrium (Bh) is a synthetic element with the atomic number 107. It was first synthesized in 1981 and is named after the physicist Niels Bohr. Currently, several isotopes of bohrium have been produced, but they are all radioactive and have relatively short half-lives. The most notable isotopes of bohrium include: 1. **Bohrium-262 (Bh-262)**: This isotope has a half-life of about 5.6 milliseconds.

Depleted zinc oxide (DZO) typically refers to a form of zinc oxide that has undergone a process to reduce the concentration of certain isotopes or impurities, particularly the radioactive isotopes of zinc. This process is often applied in various industrial and scientific applications. In the context of nuclear science, depleted zinc oxide can be used in radiation detection and shielding due to its favorable properties.
